• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (su sach)) ky nang dai moi. hieu ((ve cham) or (vu kham)) xuc va thanh vi va thiet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ky nang dai moi. hieu ((ve cham) OR (vu kham)) xuc va thanh vi va thiet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (su sach)) ky nang dai moi. hieu ((ve cham) or (vu kham)) xuc va thanh vi va thiet".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (su sach)) ky nang dai moi. hieu ((ve cham) or (vu kham)) xuc va thanh vi va thiet*.
